newb/switched from iPhone

Hey all, my name is Sara and my husband and I just got our droids yesterday. We came from first generation iPhones, so the difference in speed is already awesome. I'm looking forward to having this forum as a resource, since the droid is more complex than the iPhone was, and neither of us are techies . So I'll be grateful for any tips you'd like to share! First things first, looking for new ringtones.
